Hi
It seems, that logrotate profile works. Everything is OK - no error or
DENIED messages in log files etc. I'm testing this profile since four, five
days.
So, I just decided to paste the whole profile here, since I've added only a
few rules. It should be easier to read and eventually change the logrotate
profile in the future. Also, Mr Christian Boltz wrote, that in this case
it's OK (see:
https://lists.ubuntu.com/archives/apparmor/2016-November/010238.html).
I think, that it's important to mention: I've changed the order of rules.
For example: @{PROC} rules are now at the very end of a profile,
capabilities are near the beginning after <abstractions/*> and so on. It
just looks better and is easier to read, modify etc. That's just my opinion
and it can be changed.
I've decided to leave directories that are not in my system, but were in
the default profile. They are marked with the '#' sign and described with a
proper information about existence reason etc. If, for example there is an
user using 'privoxy' - a privacy enhancing HTTP Proxy, he can just remove
'#' sign and use one of these rules (of course depending on his
architecture etc.):
/var/lib/privoxy/log/** rwl,
/var/lib64/privoxy/log/** rwl,
One more thing about my comments: they are only for an informational
purposes and should/could be removed. So, I hope that everything is okay
even without using diff(1).
Okay, so here's an updated 'etc.cron.daily.logrotate' profile (based on
this one:
https://bazaar.launchpad.net/~ubuntu-branches/ubuntu/wily/apparmor/wily/view/head:/profiles/apparmor/profiles/extras/etc.cron.daily.logrotate):

## NOTE3: Maybe it's better to use:
#/var/lib{,64}/privoxy/log/** rwl,
/var/log/ r,
/var/log/** rwl,
## NOTE: there is not 'syslog.pid' but 'rsyslogd.pid' file

/{,var/}run/rsyslogd.pid r,

/tmp w,
/tmp/file* wl,
/tmp/logrot* rwl,
/dev/tty rw,
@{PROC} r,
@{PROC}/[1-9]* r,
}
By the way: an official profile contains rule, which confused me: "/var/log
r,". Does not should be there: "/var/log/ r,"? As we can see: missing "/".
The same thing with: /etc/subdomain.d directory - I've added '/' to these
rules. What do you think?
The last and the most important thing: can someone check this profile; I
mean from a security point of view? It's secure enough to use? Especially,
I'm thinking about permissions for a /tmp directory ('rwl,' access) etc.
Best regards.
